How can I log in if I lost my mobile phone with 2-Step Verification or changed phone numbers?
You can log in by verifying yourself via a backup email if you've lost access to your primary phone.
When logging in, click on "Verify via Email" on the bottom of the 2-Step Verification page to proceed with email verification.
Once you're in your account, please change your 2-Step Verification information to backup phone numbers or KakaoTalk.
